Comments Off on Atmospheric carbon dioxide at highest level in 3 million years

Carbon dioxide levels in the atmosphere are now at the highest level they’ve been since the Pilocene Era, 3 million years ago, when giant camels roamed arid land above the Arctic Circle. According to a new National Oceanic and Atmospheric Administration ( NOAA ) report, in 2018, the global average carbon dioxide amount reached a record high of 407.4 parts per million (ppm). NOAA points a finger directly at humans, noting that the atmospheric carbon dioxide has increased about 100 times faster annually over the past 60 years than from previous natural increases. “Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy,” the report said. “Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over the span of many millions of years; we are returning that carbon to the atmosphere in just a few hundred years.” Related: Pacific Ocean’s elevated acidity is dissolving Dungeness crabs’ shells Globally, atmospheric carbon dioxide increased about 0.6 ppm per year in the 1960s. In the last 10 years, this figure has been about 2.3 ppm per year, the study said. Carbon dioxide absorbs and radiates heat more than other major atmospheric components, such as oxygen or nitrogen. The NOAA report likens greenhouse gases to bricks in a fireplace that continue to release heat after the fire goes out. This warming effect is necessary to keep Earth’s temperature above freezing — up to a point. But once the level gets out of balance, these greenhouse gas “bricks” trap too much heat and make the Earth’s average temperature continue to rise. Carbon dioxide also dissolves into the oceans , where it reacts with water molecules to produce carbonic acid and lower pH levels. Since the Industrial Revolution began in the late 18th century, the ocean’s pH has dropped significantly, interfering with marine animals’ ability to fortify their shells and skeletons by extracting calcium from the water. “For millions of years, we haven’t had an atmosphere with a chemical composition as it is right now,” Martin Siegert, co-director of the Grantham Institute at Imperial College London, told NBC News . “We’ve done in a little more than 50 years what the Earth naturally took 10,000 years to do.” + NOAA Via EcoWatch and NBC News Image via Marcin Jozwiak

Fake trees could help in the fight against climate change

Comments Off on Fake trees could help in the fight against climate change

One of the best ways to fight climate change is to invest in trees and plants. Branches and leaves help trap carbon dioxide, effectively reducing overall pollution in the atmosphere. The only hurdle is that trees take up a lot of land and resources to cultivate, which is why scientists are turning to an alternative source in the fight against carbon emissions. Scientists in Germany just published a new study about how artificial plant life can also cut down on carbon pollution . The team created an artificial system that absorbs carbon dioxide and turns it into a product that is rich in carbon, like alcohol. The system then releases oxygen into the air and captures any excess carbon byproducts for later use. Related: How to teach children about climate change The artificial system is actually more effective than what plants and trees do naturally. In fact, some experts believe this new technology is about 1,000 times better than its natural counterpart. This is significant, because there is not enough room on the planet for trees and plants to absorb the amount of carbon we are currently emitting into the atmosphere. Although artificial trees might be the answer to help curb carbon emissions, there is one catch to the system. According to The Guardian , the cost of installing artificial trees is beyond the reach of most communities. Starting a small forest of artificial trees costs close to a quarter of a million dollars, and that is just to get the ball rolling. Scientists hope to decrease that price point in the near future, but that will only happen once technology progresses and investors get more interested in funding research. If scientists can lower the cost of artificial trees, then it might be our best option for capturing  carbon emissions. But this technology is competing against other methods of removing carbon from the air, so only time will tell if artificial systems are the answer to the growing problem of climate change.

To limit global warming to no more than 2 degrees Celsius, we’ll need to do more than reduce emissions. We’ll have to remove some carbon from the atmosphere — as a number of pioneering companies realize.

Comments Off on Massive Los Angeles methane leak declared permanently sealed

Since October, an underground natural gas storage well in Aliso Canyon , California has been belching up thousands of pounds of methane into the atmosphere every hour while the Southern California Gas Company desperately scrambled to close up the leaky pipe casing. Last week, it seemed the leak had finally been plugged , and today SoCal Gas confirmed that the leak has been permanently sealed .
